I plan on uisng lead acid batteries to power my Attitude Goggles. What would be the best way to take care of the lead acid battery? Should I power them down till they stop working before a charging, or should I immediatly charge up after every use? Also I have the Hitec charger, can anyone tell me how to figure out the charge rate and maxvcoltage shutoff, etc for that charger? There are so many settings I am not sure what would maximize my battery life. Should I ever fully discharge the lead acid before a charging as well?
